2g selection in EC25-E

How to select the 2G band only in EC25-E using AT commands?.

Please help me in the above aspect.

According to my reading of the manual:

GSM900:
AT+QCFG="band",1

GSM1800:
AT+QCFG="band",2

All bands:
AT+QCFG="band",FFFF

To lock to GSM only (inhibiting LTE):
AT+QCFG="nwscanmode",1
